Applicationfiled August 30, 1907. Serial No. 390,792.

To all whom it may concern:

Be it known that I, HARRY H. KNAPP, a citizen of the ,United States, residing at Franklin, in the county of Simpson and State of Kentucky, have invented new and useful Improvements in Files and Indexes, of which the following is a specification.

This invention relates to files or filing cases to be used in the conduct of business; and it has for its particular Object to provide an improved filing case in which invoices may be kept in the order in which payments become due so that the merchant or business man may be able at a glance to ascertain the amounts payable on any one day, and in which the invoices shall be systematically arranged in such a manner as to be automatically presented at the times when payments are due, thus dispensing with the necessity for special service, and avoiding the danger of lapsed payments.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessar-ily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may resorted to when desired. v

In the drawing, Figure 1 is a perspective view of a filing case constructed in accordance with the inventoin. Fig. 2 is a top plan view of the same with the cover open.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved filing case is in the nature of a box B, the back of which is composed of hingedly connected parts or members 1 and 2 with the latter of which the lid or cover 3 is hingedly connected the front 4 is hingedly connected with the base or bottom 5 so as to be capable of being folded down to the position indicated in Fig. 1 for a convenient inspcction of the contents of the box or case. The latter is provided with impaling posts 6 and with pivoted hook-shaped guards 7 of conventional construction coperating with the posts for the purpose of binding or securing the contents of the box or case in such a manner as to permit it to be readily inspected.

The device is intended to be used in connection with a perforator of well known construction by means of which the bills or invoices that are to be preserved may be perforated adjacent to the edges thereof so as to be readily adjusted upon the impaling posts.

Permanently mounted upon the impaling posts are a plurality of sheets 8 ofstiff tenacious paper 01' cardboard; said sheets being provided with perforations 9 whereby they are adjusted upon the posts. In pursuance of the system adopted by me it is preferred to use twenty-four sheets, being four for each of six months of the year; said sheets being reversible so as to be applicable for the remaining six months ol' the period of one full year. The sheets 8 are arranged in stacks of four and the first, second and third leaves of each stack each have portions of each of their side edges cut away to form notches 10, 11, 12, the cut away portion of the sheet next to the last sheet of the stack extending substantially one-fourth of the length of the sheet to form the notch 12, the cut away portion of the sheet above extending` one-half of the length of the sheet to form the notch 11, and the cut away portion of the top sheet extending three-fourths the length of the sheet to form the notch 10, so that when the sheets are assembled in a pile one-fourth of each side edge of the top and one-fourth of each Side edge of each of the lower sheets is exposed. These exposed portions have printed thereon dates corresponding respectively to quarterly parts of a calendar month each sheet having printed a particular date on such exposed portion upon one side and on the other side on the other portion a date of substantially six months difference. The names of the months imprinted or inscribed on opposite sides of each sheet are, respectively the first and the seventh, the second and the eighth and so on in proper sequence one sheet bearing the names of the months of January and July; the next February and August, and so on. By this arrangement, as each sheet becomes out of date, it may be simply reversed and transferred from the top to the bottom of the pile, whereit will be found in proper sequence. The date sheets are thus capable of being used indefinitely, in rotation, making a perpetual file and index.

The bills or invoices are placed upon the filing posts or impalement posts adjacent to the sheets bearing' the dates nost nearly approximately or following the dates upon which payments are due; and thus, by inspecting* a comparatively small number, the invoices payable upon any one day may be Very readily selected from the number.

The improved filing device is convenient' and tiine-saving, and is capable of perpetual use, as will be readily understood.

Having thus fully described the invention, what is claimed as new is In a filing device a case having impalement posts and pivoted card hooks in combination with leaves engaging the posts in stacks of four; the three upper Sheets of each stack each having a side portion of each side edge cut away, the cut away portion of the sheet next to the last sheet of the stack eX- tending substantially one-fourth of the length of the sheet, the cut away portion of the sheet above eXtending one-half of the length of the sheet, and the cut away portion of the top sheet extending three-fourths of the length of the sheet, so that when such Sheets are assembled in a pile one-fourth of each side edge of the top and one-fourth ofeach side edg'e of each of the lower Sheets is eXposed, and such exposed portions having printed thereon dates corresponding respectively to quarterly parts of a calendar month, each sheet having printed a particular date on such eXposed portion on one side and on the other side on the other portion a date of substantially six months difference.

In testimony whereof I affix my signature in presence of two witnesses.
